Lathe Toolpost pen/sharpie holder. BXA or any standard tool holder

<p>This pen/sharpie holder is for a lathe quick change tool post (QCTP) holder. It lets you make a mark on a part in the lathe precisely and easily. This is to help mark &amp; measure parts simply where exact precision is not necessary. One variant is for a BXA sized tool post. I was inspired by another modeler on here - that I can't find anymore - thanks to them. The other is to use in a tool holder - AXA - or whatever you are using - the pen holder is held by a toolholder similar to any lathe tool.&nbsp;</p><p>The hole is huge and will hold a big white board marker or anything smaller like a sharpie, or a felt pen, or possibly a pencil. The vertical threaded piece with a washer is a simple nut and washer for a simple height stop. Don't turn hard on the QCTP handle locking in the holder - you will break the holder - just a light touch is all that is needed.</p><p>I printed with 3 perimeters, supports, and 15% infill, 0.6mm nozzle with 0.4mm extrusion. Holes are M8. I cleaned out the holes with a M8 tap before the bolts would go in.&nbsp;</p><p>Update: pen hole is now teardrop shaped so the pen is better supported.</p>
